adhesion

When you guys are painting AR 15 magazines how do you prep them? I put mine in the sandblaster cleaned digressed and painted. When I dipped it looked good out of the tank as soon as I put in the rinse tank all of my paint came off I had no adhesion at all. using new OHW white paint on a metal magazine.

I will start cleaning before I sandblast. It could have been over activated I put down a second pass because I thought I was under activating. If it is because of the way I cleaned it what do I need to do to fix it?

I was thinking that my other parts looked good but the magazine's did not seem to get very rough on the surface. That's why I asked how you guys perp. I will go back and reperp and see what I can do. Might just hand sand and see if its better. Thanks for all the help. I will post more pic's on Saturday of the second attempt

Hand sanding is going to be tough with that surface. If you have a sand blaster, that is best... but something is wrong with your technique. Either you are out of material, or your material is not aggressive enough or something.
